I tried to make backup:
vim-cmd hostsvc/firmware/sync_config
vim-cmd hostsvc/firmware/backup_config
and I find out that result after restore host configuration:
vim-cmd -d info /hostsvc/firmware/restore_config /tmp/configBundle.tgz force
or
vim-cmd /hostsvc/firmware/restore_config /tmp/configBundle.tgz force
network of the host went to the same state as after reboot,
so
2 vswitches have NIC other two don't have NIC attached to vswitch.
Probably becouse restore command make automatic reboot after restore of the host.
